Get all readable properties for a named HVAC component (boiler efficiency, chiller COP, coil capacity, fan pressure, pump head, etc.).
AI agents call get_component_properties to retrieve information from Openstudio without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves property data from HVAC components within an OpenStudio energy model without modifying state, triggering external processes, or causing side effects. It is purely informational and falls squarely into the Read category. Low severity because misuse would only expose simulation model metadata with no destructive or operational consequences.
From the tool's definition Tool name explicitly contains 'get_'; description states 'Get all readable properties' with read-only examples (boiler efficiency, chiller COP, coil capacity, fan pressure, pump head). No modification, deletion, execution, or financial operations described.
Documented attack patterns abuse exactly the kind of access get_component_properties gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Openstudio, and nothing reaches the server without passing your rules. This is the rule we recommend for get_component_properties:
{
"version": "1",
"default": "deny",
"tools": {
"get_component_properties": {}
}
}get_component_properties is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get all readable properties for a named HVAC component (boiler efficiency, chiller COP, coil capacity, fan pressure, pump head, etc.). It is categorised as a Read tool in the Openstudio MCP Server, which means it retrieves data without modifying state.
Register the Openstudio MCP server in PolicyLayer and add a rule for get_component_properties: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Openstudio. Nothing to install.
get_component_properties is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_component_properties rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_component_properties. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
get_component_properties is provided by the Openstudio MCP server (natlabrockies/openstudio-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Openstudio, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
